Xcode 10.2.1 Command PhaseScriptExecution failed with a nonzero exit code

For me, I was removing Crashlytics, Fabric and FirebaseCrashlytics. So there was a script (Run Script) for Fabric. So since app was running that first and I had removed the framework already, I was getting this error. So I removed the Run Script tab for Fabrics and then it worked perfectly fine.

Take Pods-resources.sh from project path and paste in Terminal

sudo chmod a+x "Pods-resources.sh file path here"

Example Usage:

sudo chmod a+x "/Users/path/Desktop-path/My Work-path/Pods/Pods-resources.sh"

In my case the error was caused by the lack of space on my machine. Deleting old builds fixed the problem.

For Xcode 11, React Native development environment.
I usually have this problem when a dependency is not updated.

You can try following these steps, this usually works for me:

1- Delete your Podfile.lock (I like to use the command '-rm -rf Podfile.lock' on the terminal for this)

2- Delete your Pods folder (I like to use the command '-rm -rf Pods' in the terminal for this)

3- Delete your .xcworkspace

4- Pod install

5- Clear your project into XCode> Product> Clean Build Folder

I had the same problem in Xcode 11.5 after revoking a certificate through Apple's developer homepage and adding it again (even though it looked different afterwards):

Every time I tried to archive my app, it would fail at the very end (not the pods but my actual app) with the same `PhaseScriptExecution failed with a nonzero exit code` error message. There is/was a valid team with an "Apple Development" signing certificate in "Signing & Capabilities" (project file in Xcode) and locking & unlocking the keychain, cleaning & building the project, restarting,... didn't work.

The problem was caused by having two active certificates of the same type that I must have added on accident, in addition to the renewed one. I deleted both the renewed one and the duplicate and it worked again.

You can find your certificates [here][1] or find the page like this:

- "Account" (at the top)
- Log in
- "Certificates, IDs & Profiles" (on the left)

Also check that there aren't any duplicates in your keychain! Be careful though - don't delete or add anything unless you know what you're doing, otherwise you might create a huge mess!

Probably you should do as follow:

- Remove `.xcworkspace` and `Pod` folder
- Run `pod install`
- Delete derived data
- Clean all project (press alt before click on click)

I tried above things and it worked for me.

After trying all the **solutions**, I was missing is to enable this option in:

**Targets -> Build Phases -> Embedded pods frameworks**

In newer versions it may be listed as:

**Targets -> Build Phases -> Bundle React Native code and images**


- Run script only when installing

By mistake I had uninstalled `carthage` from my system. Adding that fixed the issue for me.

**Step 1:**
Download & install latest carthage DMG here: [Carthage](

)

**Step 2:**
```ruby
carthage update --platform iOS --cache-builds
```
**Step 3:**
Run project & enjoy. :)

I was able to resolve this error by remove file in Pods -> Targets Support Files -> Pods-AppName -> Pods-AppName-frameworks.sh. After removing that file again install pod using command pod install.

OR.

Try this:

-> quit xcode
-> install pod(again)
-> start xcode
