Xcode 12 - No architectures to compile for (ONLY_ACTIVE_ARCH=YES, active arch=x86_64, VALID_ARCHS=arm64e armv7s arm64 arm7)

Question

Since I update Xcode to Xcode 12, I've got this error when I build :

Check dependencies
No architectures to compile for (ONLY_ACTIVE_ARCH=YES, active arch=x86_64, VALID_ARCHS=arm64e armv7s arm64 arm7)

I try a lot of things :

• Uninstall/reinstall Pods via pod install
• Build Active Architecture Only to No or to Yes for Debug and Release
• Same thing for Pods project

Don't know what to do. This error come when I want to launch on iOS 14, but in iOS 13.7 this work perfectly without change.

-- EDIT --

I solve my problem by adding arm64 arm64e armv7 armv7s x86_64 to VALID_ARCHS, both in 'MyProject' and 'MyProjectTest', and it work now.

Solution 1

If you can't see "VALID_ARCHS" in BuildSettings. You can click the plus button.

click "Add User-Defined Setting"

Input setting name "VALID_ARCHS" , input value "arm64 arm64e armv7 armv7s x86_64"

Solution 2

Theorectically it should be enough changing debug from yes to no.

But as you said it did not work it must be that you have to set VALID_ARCHS to what you have plus x86_64.

Solution 3

M1 Mac: run Xcode in rosetta(by going to the .app file and clicking "get info" the click "open using rosetta"

Solution 4

Go to your App's target and select 64 bit standard architectures in Architectures section. See attached screenshot

Solution 5

run Xcode in rosetta(by going to the .app file and clicking "get info" the click "run under rosetta"

try to run on actual device, this issue is on simulator

[Pentagura]

@MZubairShamshad Ok I will test that, but how make it work on simulator ? I've not all Apple devices for real ^^

[Pentagura]

I haven't this choice to select, what does I need to do to add this ?

[Ali Mehdi]

Add "$(ARCHS_STANDARD_64_BIT)" this in other option in Architectures

[Ali Mehdi]

Did you clean build?

[Ali Mehdi]

what was your previous value for architectures?

[Pentagura]

Standard architectures - $(ARCHS_STANDARD)

[Pentagura]

I also try to put Debug to "No", but I haven't "VALID_ARCHS" in XCode, I don't found it

[Hola Soy Edu Feliz Navidad]

@Gargantua Pay attention on the top if it is showing all options or only the basic ones.

[Pentagura]

It's the case, "All" is selected

[Pentagura]

Thanks for your complete answer, but I doesn't work anymore... I precise it works since the beginning in a real device. The only problem is for emulator.

[Pentagura]

I finally solved the problem. I do exactly what you do, but for "MyProjectTest" to and now, it work !

[Akhil]

@Gargantua i also have this issue. i tried the same but still i am not able to run my app on simulators. Please help

[Pentagura]

As I say, I only add what @ShaoJen Chen tell and it work ! I had those lines on"MyProject3" and "MyProject3Tests"

[Umeumeume]

I added the VALID_ARCHS in all(project,target,AppTest), but no luck for iOS simulator. it worked only for the device. Any help?

[Umeumeume]

I have this issue only on M1 MacbookAir, not on my iMac.

[Xavier Ojeda Aguilar]

@NonUmemoto same for me in my M1. I have this issue because I'm trying to solve other problem, but int he thread they suggest to use Build legacy, and when I tried to use that, I get this.

How to run the app in rosetta

[Naresh]

how to achieve it, can add some screen shots.

[Naresh]

I have followed your steps and added x86_64 in VALID_ARCHS but no use. How to resolve in Xcode 12.2....

@sejn You need to first have a M1 or M2 Mac to select that option as per the given answer. If you run Xcode in Rosetta, then the binaries will be running under 'Intel'. You can check by opening Activity Monitor, under the Kind column, see if it says Apple or Intel.
