Warning: "This app will not work with future versions of iOS" - ios

I have an iPad with iOS 10.3 installed. Some apps are triggering a popup warning:
"SomeApp" needs to be updated.
This app will not work with future versions of iOS.
It is something related with 32 or 64 bits? I am using last version of Xcode.

It's probably related to 64bit support. Make sure that in your build settings under architectures ARM64 is present.

Xamarin Release Build Archirecture

I recently Updated the VS for Mac. After Wards I cannot Select Build Architecture Armv7 + arm64. It allows Arm64 alone. Since my app is not going to be pushed in App Store i do want these s=architecture to be selected as my build configuration. How to sorted out this
You can always manually edit .csproj file and write whatever value you want.
Apple deprecated 32 bit support in iOS 11. See https://learn.microsoft.com/en-us/xamarin/ios/platform/introduction-to-ios11/updating-your-app/architecture-changes
32-bit apps will not launch in iOS 11+ and we actually can't compile the 32 bit slice with newer Xcode. This is why you can't just edit the csproj, you'd need Xcode 9.4 for that.
Even if you don't deploy to the store you shouldn't have any issue with a 64 bit only App.

Submitting iOS app for iPad-1 with iOS 5.1?

EDIT: My answer is provided below
I was developing an educational app which I was targeting specifically for iPad-1 devices, because I think schools can take advantage on these 'old' devices.
However I'm afraid that nowadays it is not possible to upload apps which support iPad-1 (which is stuck with iOS 5.1).
What happens when I try using Xcode 6.4 to submit, is one of the two:
If I include the standard architectures (both 32 and 64 bits), I'm getting an error saying that apps with 64-bits can't set their target to iOS 5.1.
If I remove the 64-bits support, I'm getting an error saying that Apple do not allow apps without 64-bits binary.
I was trying to search the internet but didn't find much info. Any idea please?
EDIT
I was trying to use the standalone app loader but it didn't change anything because the validate is done by the remote server. For the second option above, I was getting this:
ERROR ITMS-90086: "Missing 64-bit support. Beginning on February 1,
2015 new iOS apps submitted to the App Store must include 64-bit
support and be built with the iOS 8 SDK. Beginning June 1, 2015 app
updates will also need to follow the same requirements. To enable
64-bit in your project, we recommend using the default Xcode build
setting of “Standard architectures” to build a single binary with both
32-bit and 64-bit code."
ANSWER
I got an answer at the developer forums of Apple, so copying here:
Although not in the drop-down box of the deployment targets of Xcode, we need to set the deployment target to be 5.1.1 in order to allow installation on iPad-1 devices.
This is because 5.1.1 is compatible with iPad-1, and is capable of reading dual-architecture binaries.
One thing to consider is that it will not be possible to use TestFlight for testing on these devices, because TestFlight is only compatible with iOS 8 and up. But testing can be taken in other means, like direct-install from Xcode.

Appstore Architecture warning

I developed first version app in xcode 5 and the second version work with xcode 6 , in this version i have drop box sdk1.3.13 it is not support the arm64 so i removed this from valid architecture now my app work fine and my STANDARD ARCHITECTURE is armv7,arm64 and my VALID ARCHITECTURE is armv7 , armv7s. I submitted my app into appstore in my validation warning is
The archieve passed validation with several warnings
iTunes store operation failed
Missing 64-bit support. Starting February 1, 2015, new iOS apps uploaded to the App Store must include 64-bit support and be built with the iOS 8 SDK, included in Xcode 6 or later. To enable 64-bit in your project, we recommend using the default Xcode build setting of "Standard architectures" to build a single binary with both 32-bit and 64-bit codes.
My Question is
1.If i will submit my app without clear this issue the appstore will accept or not?
2.Please clearly explain why the warning is occur , what mistake i did in my STANDARD ARCHITECTURE and VALID ARCHITECTURE
3.Why the Dropbox sdk 1.3.13 not supported the arm64 architecture?
Here is what Apple says:
Starting February 1, 2015, new iOS apps uploaded to the App Store must include 64-bit support and be built with the iOS 8 SDK, included in Xcode 6 or later.
To enable 64-bit in your project, Apple recommend using the default Xcode build setting of “Standard architectures” to build a single binary with both 32-bit and 64-bit code.
So, Apple may reject your app if your app has this issue at the time of submission.

Missing 64-bit support for iOS application

I'm getting warning for 64-bit support missing. The whole message is like below:
Missing 64-bit support - Beginning on February 1, 2015 new iOS apps submitted to the App Store must include 64-bit support and be built with the iOS 8 SDK.

I've done changes like attached image for Valid Architectures.
If i try to Archive the build with supporting arm64. I'm getting following errors.
If i will remove arm64 from Valid Architectures, it will work fine and submitted successfully to iTunes Connect but i get mail from iTunes that binary is missing 64-bit support.
I have done googling but not able to get exact solution. Please help me for getting out of this issue.
Any help will be surely worth appreciate.
Thanks,
Amazon iOS SDK offers 64bit support since the version 1.7.0
https://aws.amazon.com/releasenotes/iOS/7003308162044672
Simply use their latest version 2.1.0 , and it will compile with arm64 flag.
That means your library is not compiled for 64 bit, arm64 and your app is expecting it,
There should be new version of that library which supports arm64, just check the developer's web site.
http://aws.amazon.com/mobile/sdk/
Simply update valid architectures and add arm64 flag in Xcode it's not the only step that you need to make an application 64-bit compatible.
Your log is telling you that one library at least it has not been compiled for 64-bit. So update your libraries, in particular from the logs I think you need update the Amazon library.

Xcode 4.5 and iOS 4.2.1 incompatibility

The latest release notes indicates 4.2.1 and lower will not be supported, we now have to use 2 version of Xcode to develop when supporting older devices?? This is going to be difficult to support older devices if we want to develop iOS6 AND support 4.2 and lower.
I don't think Xcode 4.4 will support iOS6. So this is the issue. How would developers easily support these platform without so much hassle?
You can do this, but it requires some minor Xcode hacking, and some sacrifices. Depending on what you mean by "support iOS 6", this may or may not be sufficient for you. If you just want your app to run on iOS 6, then this should work. If you also need your app to incorporate new iOS 6 features, then it won't.
(Note for others who don't have a problem using multiple versions of Xcode: this similar question has answers that do allow you to also use new iOS 6 APIs and directly target armv7s)
See basic instructions on chpwn's blog here (but read the rest of this below, too!)
Basically, you can use Xcode 4.5 to build for iOS 4 and above, but then you can't take advantage of the new iOS 6 only features. So, you're really building for iOS 4 and 5, and assuming that the app will run fine on iOS 6 (which should be true, but you'll need to test this yourself).
You'll need to copy the iOS 5 SDK folder
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.*.sdk
from an old Xcode installation (which you'll need to keep around briefly, or reinstall to a non-standard location). You'll then set the Deploy Target in your Build Settings to iOS 4.0 (or whatever minimum OS you want). You may need to open the project.pbxproj file in a text editor to set this manually:
IPHONEOS_DEPLOYMENT_TARGET = 4.0;
You'll also need to set the Architectures to armv6 and armv7. You cannot directly also target armv7s. But, that doesn't mean your app won't run on iPhone 5. armv7 executables should run on iPhone 5, simply without any optimizations added in armv7s. It's just that compatibility doesn't work in the other direction (e.g. armv7 executables don't run on an armv6 iPhone 3G).
There's also a step that might be necessary, that's not mentioned in chpwn's blog. You may get these warnings (which really are errors, because Xcode won't generate your executable properly):
warning: no rule to process file '$(PROJECT_DIR)/main.m' of type sourcecode.c.objc for architecture armv6
In order to fix this, you'll need to setup a custom Build Rule for your target that tells Xcode to use LLVM GCC 4.2 to generate armv6 code. Define the rule for files matching the pattern *.[mc]:
This will be a different compiler than the Xcode default, and you may need to adjust some of the syntax in your Objective-C code. Even though many people wanting to do this probably wrote their apps before ARC, it is important to note that LLVM gcc 4.2 does not support ARC.
Finally, you probably will still see warnings from Xcode about iOS deploy targets less than 4.3, and armv6 not being supported. Those, I found, were not problems, and could be ignored:
Running lipo -info on my app executable after this shows the desired result:
lipo -info MyAppName
Architectures in the fat file: MyAppName are: armv6 armv7
Xcode 4.5 makes iOS 4.3 the earliest supported operating system, which effectively orphans the original iPhone and the 3G.
If you want to support iOS versions earlier than 4.3, you will need to keep around a 4.4 version of Xcode.
To be a bit clearer : you cannot easily (meaning Xcode does not out-of-the-box) support pre-4.3 devices and use iOS 6 features in the same app. That's because iOS 6 features require XCode 4.5 which also sets iOS 4.3 as the minimum supported OS.
So, you have 3 choices :
Continue using XCode 4.4. You'll be able to target pre-4.3 iOS. You won't be able to take advantage of iOS 6 features, but your app should run fine on it assuming you perform adequate testing on actual iOS 6 devices.
Migrate to XCode 4.5. You won't be able to target pre-4.3 iOS, but you'll be able to take advantage of iOS 6 features.
Make two versions your app. Build one version with XCode 4.4 (as in option 1), and the other with 4.5 (as in option 2). From the point of view of distribution, these will be 2 separate apps, they'll each have their own bundle ID, etc. You will have two entries in the app store.
If you are comfortable going beyond what is supported directly by Xcode, see Nate's answer.
The original iPhone and iPhone 3G are the only devices that don't support iOS 5. The iPhone 3G is now 4 years old. You may want to consider dropping support for iOS 4. If you don't want to do that, I think you'll have to develop in two different versions of Xcode.
I assume that the dropped support for iOS 4.2.1 is not the core problem. In fact, I tried to work around this and do the following:
Build the app with iOS 6 SDK, setting deployment target to iOS 4.2.1 (which works).
Pack the app for ad hoc installation and install the app on an iOS 4.2.1 device (iPod touch 2G).
Test the app.
However, installation fails. The reason here is - afaik - not the iOS version. The reason is the architecture. XCode 4.5 no longer allows you to build for armv6. It only builds for armv7. On the other hand: all device which have armv7 or better can run iOS 5. The only devices which do not support armv7 are iPhone, iPhone 3G, iPod touch 1G and iPod touch 2G.
So for me the question is: can you build for armv6 with XCode 4.5 and iOS 6 as base SDK?
Edit: Which you cannot do, because the iOS 6 base SDK is not available for armv6. Right?
Try to set the project settings manually using IPHONEOS_DEPLOYMENT_TARGET=4.0. However, I don't know if there is any side effect.
I think that targeting to 4.3 is the best choice, according to ios version statistics
