I m planning to purchase iPhone device for iOS development. And my pocket budget is too less... :(. So if i purchase iPhone SE, then is it work for me. Like, can app developed on iPhone SE will run perfectly on iPhone 6, 6s, 7 etc.
I m really confused so please help me to sort out this issue.
Thanks
can app developed on iPhone SE will run perfectly on iPhone 6, 6s, 7
Testing whether your interface is laid out correctly on different screen sizes can be done using the Simulator. However, it's best to test also on a device, as a device can do things the Simulator cannot do, and things like memory and speed and energy usage can only be tested on a device.
Most developers have just one device, or perhaps two, an iPhone and an iPad. You should get a device with any features you intend to use in your app and that cannot be tested in the Simulator; for example, if you're going to use 3D touch, or the barometer, an iPhone SE isn't going to do you any good, because it lacks those features. But if you're willing to exclude features you cannot test, you should be fine with an SE.

I recently gave my iPhone 4 to a friend so I don't have a Retina 3,5" Device anymore.
I wondered if theres a way without much tweaking the app code to get the 3,5" Version on the iPhone 5(like an App which isn't optimized).
If you do not include (or temporarily remove) Default-568h#2x.png if will run as a 3,5" app.
The simplest way would be to test on the iPhone simulator and change the hardware from retina 4 inch to retina 3.5 inch!
Or ask your friend to borrow their phone and test it on the device which involves certificates so it's slightly more inconvenient.
Either way, it's not too hard to test on multiple devices. Additionally, if you have an iPod touch that is older than the 5th generation, that works too.
Generally you can purchase, cheaply, used iPod touches online to use for development testing. Good luck!
I am building an iOS application for public release, and I would like to develop it against iOS 4, as I see from the instapaper stats from November that iOS 5 has a 48% market share, which is good, but my app will probably not be used by these early adopters, and it's probably not going to be enough to force them to upgrade.
The issue is that I only have an iPhone 4S, which shipped with iOS 5. I have been unable to find an iOS build for my 4S, which upon reflection makes sense. Nontheless, I'd like to know if there is some sort of unofficial build for the 4S or some way to make the iPhone 4 version work on the 4S.
I'm pretty sure that the answer is going to end up being "Buy a 3GS/iPod touch for development". Would that necessarily be worth it or should I just tough it out? I'm pretty sure that most iOS 4 users will upgrade eventually. Does anyone have any stats on how long it took iOS 3 users to move on?
I would still suggest getting a used iPhone 3GS. Even if you are able to install iOS 4 on the 4S you still wouldn't be able to do any performance testing, but it's highly likely that someone who still uses iOS 4 has a 3GS.
For your first cut testing, you can use the simulator which, will allow you to test for iOS 4.3
Ideally you need to get hold of the appropriate devices to test your app. You say you're supporting iOS 4, but do you mean 4.2 or 4.3? If 4.2 then you'll be supporting iPhone 3G, if 4.3 then 3GS upwards.
There are testing services out there, just search "iPhone testing services". I've never used them myself, so can't vouch for any of them, but the cost may be less than investing in actual devices.
I kept a 3G and 3GS for testing, but to be honest, even though my main app supports 4.2, I rarely do any testing for older OS versions outside the simulator. I gave the 3GS to my father on condition he tested for me when asked… but of course I had to upgrade it to iOS 5 for him, so it's of little practical value, apart from testing at different screen res.
I would suggest you develop your app with minimum version 4.0 (or other) set. Then you test that on your iOS 5 iphone. I did it with my apps and it works great.
You can test on the lower version simulator or for final testing you could borrow a friend's device or similar.
As I understand (and believe), the compiler would stop you if you included features that are not 4.0 (or the set version) compatible.
Buying lower iOS is not worth it. If you can you should borrow it. In the simulator you can also make the iOS version to lower version to test. Also you can try ad hoc distribution to check how your app performs on other ios before releasing on appstore
Today i was going through an website and found something over this iphone and ipad development projects. I had a question whether a developer requires an iphone to actually work with or is there any other simulator type device where we can test it out too.
It would be also great if you can share some docs on getting started.
Thanks.
We have applications that run without a problem on the simulator and crash on the device, so I'd say yes. You might delay it for a bit, and work on the main aspects and buy the device later, but you should have it.
You should start at the iPhone Dev center and depending on your knowledge of Objective C, try some tutorials for it. One of the first tutorials I read about Objective C, and which helped me a lot, is here
You can simulate certain gestures and actions while running the simulator: the developer.apple article is here
You can test many aspects without having an iPad.
There are, however, some that you cannot.
Touch
Acceleration sensor
3G internet
much more
I strongly recommend buying an iPad / iPhone to test the user interface. A PC and the iPad have very different user interaction models, it's hard to create a native feeling app without having an actual device.
You can develop with the iPhone SDK which include an emulator. http://developer.apple.com/iphone/index.action but you would probably be better off having one of the devices if your developing a complex application. For working with Camera's or sensors it's best to have a real device to test you code on.
I dont think there are any devices that run the iPhone system. If there are they are probably illegal.
There is emulator build in XCode.
You dont need a device to run your code etc, but try to test the touch and other sensors in the emulator.
So basically if you are planning on shipping something bigger than helloworld you probably should get the Apple device.
There must be an emulator (I'm not sure, that's a guess), but as with any other development you better have a real device as well so that you have better chances of reproducing problems customers will report.
For iPad development you must have Mac OS X 10.6 Snow Leopard
Now, I'm developing on iPhone SDK3 and iPodTouch 2G. iPodTouch 2G can't do full function of iOS4. I want to change iPhone SDK4 development.In july, iPhone 4 and iPad will available in singapore. So, What should I buy iPad or iPhone 4 for iPhone SDK 4 ?
What different between iPad API and iPhone 4 API ?
How about market ?
Can I write iPhone app with iPad ?
Each version of the OS has the same API for all devices, but some of them don't support all all features. For example, the UIImagePickerController allows the user to select a photo. On an iPhone, they can take a picture with the camera or pick an existing photo from their Photo Library. With iPad and iPod Touch, there is no camera, so the user could only pick a picture from their Photo Library.
If you are relying on hardware features such as camera, compass, gyroscope, accelerometer for your application, you'd need a device that has this feature as the emulator does not them.
iPhone 4 has all of the hardware features of all iPhone, iPod Touch and iPad devices. Buying an iPhone 4 with or without contract is going to cost some money, but if you're developing an application you can recover the cost with sales of your app or iAd revenue.
If your application does not need specific hardware, then the best choice for you is going to depend on cost and whether you will use the device each day. A second-hand iPhone 3GS will do almost all iOS 4.0 features except front-facing camera and gyroscope.
The iPad runs iOS 3.2 currently. Apple has said that 4.0 won't be available for the iPad until "Fall" (aka Autumn). So if you want to test 4.0 apps in July on a real device (not just the simulator), you'll need an iPhone 3GS or 4.
I'm not experiences in ObjectiveC but I guess it really depends of what you want to do. You can do everything in the emulator so I guess you want the real devices to do proper testing over your applications. The only difference between both is that iPad doesn't have the new 6 axis acelerometer and doesn't have frontal camera. Apart from that the API should be the same (removing the support for phone calls oviously). I dont know what apple is going to do about games and so on but I guess the solution will be the same than between 3gs Iphone and IPad. Since the Ipad screen resolution is still bigger than the new Iphone one, you should be able to run any iPhone application (even the new ones) in your IPad (unless they use frontal camera or any other functionality not present in the iPad).
In resume, If you only want the device for development I whould buy an IPad since you can develop and test IPad and IPhone applications, so it is much more versatile. If you have an IPhone forget about testing IPad apps since you have not enough resolution.
Hope it helps.
Can i develop and test iphone native applications on windows pc and testing in any iphone simulator? If no then, What is minimum hardware and software requirements for Iphone native apps development. I want to make development environment setup in minimum possible price.
Intel-based Mac (can be a Mac Mini; I prefer a MacBook Pro that I can take with me and develop in a variety of locations, office, a playground while kids play, when I travel...)
Xcode (free download)
Optional software I use all the time:
Adobe Photoshop (or similar bitmap
and/or vector based image editing
software)
Logic Pro (or similar sound editing software with a library of
sfx)
The optional stuff is not something I needed as much for other software development. It seems that on the iPhone, the audio/visual experience is as much a selling point as the functionality of the app.
As for whether a simulator is good enough, I have to say NO! The iPhone Simulator is adequate for simple apps, but it operates at a faster processing speed than iPhones and iPhone Touches, making your app run faster than it would in the real world. It also behaves differently in a number of ways, which makes it important to have a 'real' alternative. In fact, during a day of development, I may use the iPhone Simulator for 80% of the test builds, and an iPhone OS device for the other 20% in order to make sure I am on the right track. I have two iPhones with 3.0 and 2.0 software, plus two iPod Touches. The 2.0 iPhone is the 3G, which is the slowest, then the iPod Touches are a bit faster, and the iPhone 3Gs is the fastest of the bunch. I test with all to make sure the user experience doesn't get too sluggish on the slowest.
You basically need an Intel-based Mac. You can find used Mac mini's for cheap (and use an existing monitor and USB keyboard/mouse).
If you're serious about iPhone development, buy a refurbished Mac Mini and a refurbished iPhone to test it on. If you just want to play around first, search Stack Overflow for the thousand other questions that answer how to do iPhone development on windows.
If you're serious about iPhone development, buy a refurbished Mac Mini and a refurbished iPhone to test it on.I prefer to use mac-Mini or an intel based mac.You can do almost all testing on Simulator except these few which requires original hardware(Gps,Opening another iPhone app from your native app).In terms of memory simulator doesn't have it's own memory it depends on your hardware memory so if you want to develop a good bug free app go purchase an iPhone.
