I'm using Swift 2.3 in my project. Yesterday, I updated Xcode to version 8.3 but my project can't build successfully any more. I got this error message.
“Swift Language Version” (SWIFT_VERSION) is required to be configured correctly for targets which use Swift. Use the [Edit > Convert > To Current Swift Syntax…] menu to choose a Swift version or use the Build Settings editor to configure the build setting directly.
Please help me! Thanks!
It is said in release note clearly that Xcode 8.3 doesn't support swift 2.x any more. You can either choose to use wizard to update your code to swift 3.1, or go back to Xcode 8.2.1.

That's true.
You have to convert your code to Swift 3. Or try to download a lower version of Xcode.

I am currently trying to add firebase to my Xcode project. I am using Xcode 11. The problem is with the actual cocoapods because now none of my projects using cocapods will build. im currently running cocoapods 1.9.3. All my errors fall under GoogleDataTransport and it says theyre all "lexical or preprocessor issue"s. Any help would be great!
I think this error is related to this issue.
To fix it, you have to modify the build settings.
Select your Pods Project
Go to Build Settings
Set Quoted Include In Framework Header to NO

SWIFT_VERSION '3.0' is unsupported, supported versions are: 4.0, 4.2, 5.0. (in target 'Alamofire')
I am getting this message and my app build fails. Kindly help me out as I have all things up to date.
Go to your POD's project Settings, select your target (Alamofire in this case), then in the Build Settings Section, search for swift language version and change it to 4.2

This is happening after I upgraded to Xcode 5.0.1. When ever I try to stop the xcode it is not stopping. The simulator is remaining as blank. How do I resolve this issue?
I get this sometimes. It is entirely unrelated to project code and is some bug or issue with XCode. It also happened in earlier versions (XCode 4.x). No solution but to force quit.
Surprisingly, what worked for me was going to iOS Simulator menu, and pressing "Reset Content and Settings".

I am beginner in iPhone.
I want to make the iPhone app that compatible for all iPhone versions like 3 and above.
Please help me What to set in the project to make it compatible to all version.
Thanks in advance.
You should set the deployment target in the target summary.
Edit: Xcode 4.5.x only supports iOS 4.3 and later so you can't support iOS versions below it.
Edit 2: If you are using and old version of Xcode this might be helpful for you. iOS 3.x support in Xcode 4
But you should think twice before writing an application that targets iOS4 and above.
Targeting to old versions of iOS means that you must not use any of the API's of the next iOS versions such as ARC and auto layout. As a result your code will be harder to maintain and some features would be impossible to implement.
Before going on with it, think about how many users will you satisfy by supporting iOS4. Read these thousand words from apple and then decide for yourself
