iPhone build configurations - Entitlements.plist - iphone

Is it possible to have two Entitlements.plist files so that the one which the debugger can attach is associated with the debug build configuration whilst the one without would be associated with the release configuration?

Sure. In the build settings, you can specify a different Entitlements plist file for specific build configurations. Just set the appropriate one for Debug and a different one for release/distribution etc.
The settings is called "Code Signing Entitlements" or "CODE_SIGN_ENTITLEMENTS" depending on whether you have show names or titles set.
Just specify the name of the Entitlements.plist file you wish to use, eg:
Entitlements-Debug.plist
or
Entitlements-Distribution.plist

Swift: How can we use different Info.plist file for another Scheme

The A scheme use Info.plist file but scheme B can not.
Can I create another one for scheme B?
If your scheme is a specific build of your app (let's say your staging or dev app instead of the production) you can.
You will have to specify which plist file to use though.
Select your project (top left), go to your target, build settings and on packaging you can specify the info.plist file that will be use by your scheme.
Hope it helps

iOS Link Binary with library for debug only

I have a bit of a problem with setting different configuration for my project. I have two versions of the same static library. One has logging enabled, the other doesn't.
I am using two different xcconfig files for Debug vs. Release. In these files I specify the library and header search paths for the two variants of the static lib. So far so good.
However, in my build settings I can't see a way to conditionally link the actual library. I.e use the debug variant for Debug and the release for Release.
Any ideas?
You need to link the library using the "Other Linker Flags" build setting, rather than the standard "Link Binary With Libraries" UI. The build setting can be changed depending on the configuration:
Click the triangle and you can give different values for Debug/Release. You will need to use the -l flag. For example, for a filename of libMyLib.a use the flag -lMyLib. You may need to edit the "Library Search Paths" to search the appropriate location.
If the filenames for the debug and release version are the same and you don't want to change them, put them into their own lib/Debug and lib/Release directories respectively. Then edit the "Library Search Paths" build setting adding either "$SRCROOT/lib/Debug" or "$SRCROOT/lib/Release" for the appropriate configuration.

How to configure independent sets of runtime settings in Xcode

My iPhone application connects to three different servers, say: production, staging and testing. There is a bunch of configuration values that the application uses depending on to which server it connects to, e.g. Facebook App ID, TestFlight team key, etc.
I'd like to have all the settings in GIT and only select which configuration the application supposed to use when compiling or releasing. For example, when testing is selected, Product -> Run in Xcode runs the debug version of the app connecting to testing, and Product -> Archive creates the IPA file with the release version that also connects to testing.
I don't want to create more build configurations than debug and release (because that would mean 6 different combinations of build configurations/run-time configurations). The ideal solution, as I see it, would be that I have three schemes: production, testing and staging, and each scheme selects one of three Info.plist files to use with the application. That would allow me to not only define different run-time settings, but also different application versions or bundle identifiers depending on the back-end server. But it doesn't look like I can configure the Archive action in any other way apart from selecting a different build configuration. Any ideas if that could be achieved in any way?
Edit: To make it a bit more clear, production/staging/testing is the back-end server, not the version of the iOS application. The iOS app comes in two versions: debug/release. In other words I may want to run a debug version of the application connecting to the production server for example to debug a crash caused by JSON returned from that server. I could have named the servers as A, B and C for the sake of clarity.
A good way to do this would be with build configurations and C macros. This avoids having to create a separate target for every configuration which is not really the correct use of targets.
First you want to set up the configurations at the project level:
You can create different configurations for debugging, enterprise distribution, and any other type of special build you want.
Next you can define some macro flags for each configuration which will be passed to the compiler. You can then check for these flags at compile time. Find the "Preprocessor flags" build setting at the target level:
If you expand the triangle you can define different values for each of your configurations. You can define KEY=VALUE or just KEY macros here.
In your code, you can check for the existance of these macros, or their value (if there is one). For example:
#ifdef DISABLE_FEATURE_X
featureXButton.hidden = YES;
#endif
// ...
#if FOOBAR_VISIBLE == 0
foobarView.hidden = YES;
#elif FOOBAR_VISIBLE == 1
foorbarView.hidden = NO;
#else
#error Invalid value for FOOBAR_VISIBLE
#endif
You can pass in string values as well, which must be wrapped with single quotes in the build setting, e.g. DEFAULT_LOCALIZATION_NAME='#"en"'.
You can also configure which configuration is used during Debug and Archive time using the Schemes editor. If you choose "Run" or "Archive" in the Schemes editor you can select the appropriate configuration.
If you need to parameterize entries in the Info.plist file, you can define their value using a custom build setting. Add a custom build setting for your target:
And then give it an appropriate value for your different configurations:
Then in the Info.plist file you can reference this setting:
Note that the one limitation of this approach is that you cannot change the following items:
Settings.bundle
Additionally, in older versions of Xcode without asset catalog support, you cannot change the following items:
Icon.png
Default.png
These cannot be explicitly defined in the Info.plist file or anywhere else, which means you need different targets to change them.
I would suggest using different build targets for each environment. I successfully used this model before. In your project's settings you can duplicate the current target and change the build settings as needed. There's an Info.plist File property that will let you change the default plist for that target.
After that, you can create a scheme for each environment that will use the according target.
You can get a step further and use different bundle id for each target and different names. That will allow you to install both the staging and the production builds on the same device for example.
The only downside in this is that you have more work when you want to update provisioning profiles.
Here's a much easier solution if the concerned libs allow to set the keys in code, meaning that you can have production value in your plist file, but change them in your AppDelegate (or whichever file they are first used in).
Works with facebook, twitter and google sdk at the moment.
Ex:
#ifdef DEBUG
// Facebook
[FBSettings setDefaultAppID:#"SandboxID"];
// Fabric / TwitterKit - must be called above [Fabric with:#[TwitterKit]];
[[Twitter sharedInstance] startWithConsumerKey:#"SandboxKey" consumerSecret:#"SandboxIDSecret"];
#endif
Same in Swift, just use #if instead of #ifdef.
Note about Facebook This worked with version 3 of their SDK, I'm not sure it's possible with later versions.
It is probably very low tech but I just have a method called apiURL() that returns the URL of the API I want. I have localhost, stage, and production and I simply uncomment the one I want. It's worked well for me so far. I've only forgotten to switch it back a few times. Oops.

XCode4: Project settings differs from Targets settings?

I don't know the reason but this happens at times. I am setting bundle id correctly and also installing mobile provisioning profile correctly but sometimes build settings for Project doesn't detect my certificate automatically(when I select iPhone developer in signing) but it does for build settings of Targets! I don't understand how this could be possible? AFAIK automatically detection of certificate related to bundle id in plist file that correspond to set in certificate which is I am making sure they both matches! Could anyone think of any scenario where Project and Target differs in signing?
Thanks.
Regarding Project and Target settings; I believe the reasoning here is that one Project can contain multiple Targets if needed. Its usually one in the general case, the Target for your main application.
Therefore, the Project Settings will be the big, overall settings which apply to ALL your targets and I believe you will be able to customize them for different targets if needed.
The general guideline I follow is, I always set the certificates and profiles etc in the Project Settings, then go to the Target settings to verify that they have been applied (sometimes they are not automatically applied); and if not, reapply them there. This always works out for me without a prob.

Distinguishing development iPhone app versions

I like to keep a store-bought version of my iPhone apps on my phone so that I can reproduce any customer issues that come up, but I obviously also want to run the most current development version. I can install both (one from iTunes, one from xCode) but I'm interested in ways that I'm better able to tell the two apart. I could just change the name or icon temporarily, but that doesn't seem very failsafe, i.e. I might forget and ship it with the wrong icon.
Is there a happy funtime developer way to do this?
I was inspired by Eric's idea of adding a user-defined setting to the project but I didn't want to run a script every time I built the project.
We know that the iPhone looks for icon files named "Icon.png" by default. It turns out that the "Icon File" setting in the project plist isn't necessary at all if you've named your icon properly. However, if there is no file named "Icon.png" in the project, xCode looks at the value of the "Icon File" setting.
I set a user-defined setting in "Debug" called "Icon_Name" to a non-standard icon name, "DevIcon.png" and "ReleaseIcon.png" for the "Release" config. The "Icon File" setting in the project plist can now be set to ${ICON_NAME} and will take on the value of whatever config file we're using. Now building under two different configurations does use two different icons.
Edit: For multiple icons (high res, small, ipad, etc) I made a slightly different approach. The user-defined setting is now "IconPrepend" which is "Dev" for debug and "Release" for release config. I'm now using "Icon Files" (rather than "Icon File") in the info plist which takes an array of strings. Each string is prepended with ${ICONPREPEND} so that debug configurations look for "DevIcon.png" or "DevIcon#2x.png" and release configurations look for "ReleaseIcon.png" or "ReleaseIcon#2x.png".
Here's an idea - if you set a User-Defined Setting in your Project Build properties for Debug only along the lines of USE_DEV_ICON=YES (or something). Then, using the "Run Script" option in your Build Target you could copy different icons based on which Active Configuration you called.
Something along the lines of (pseudo-code):
if ($USE_DEV_ICON == YES)
cp DevIcon.png Icon.png
else
cp RealIcon.png Icon.png
Then every time you build, depending on the active configuration, it will copy the correct icon.
Most probably there is no other way. Your app store version and development version is completely different to the OS. If you want to distinguish, you need to change the icon or name. You can also include some debugging label (e.g. version number) in your development version, but you may also forget to remove this.
Maybe you'd just buy a second iPhone? Seriously. On your place I'd ask the same question as you do, but I will definitely take such a solution in mind. If I was an iPhone (or whatever other specific platform) developer, I'd most probably have more than one.
Couldn't you make a new target which has a different Bundle name in the Info.plist file, and use this target whenever you want to build the app to run on your iPhone?
