Error: "The sandbox is not in sync with the Podfile.lock..." after installing RestKit with cocoapods

Solution 1:

I was able to fix that by updating CocoaPods.

I. Project Cleanup

1. In the project navigator, select your project
2. Select your target
3. Remove all libPods*.a in Build Phases > Link Binary With Libraries

II. Update CocoaPods

1. Launch Terminal and go to your project directory.
2. Update CocoaPods using the command pod install

Solution 2:

After many attemps I managed to fix this problem. Variable ${PODS_ROOT} was not set and I do below trick. Go to Build Phases -> Check Pods Manifest.lock and replace

diff "${PODS_ROOT}/../Podfile.lock" "${PODS_ROOT}/Manifest.lock" > /dev/null

to

diff "${SRCROOT}/Podfile.lock" "${SRCROOT}/Pods/Manifest.lock" > /dev/null

It helps me.

Solution 3:

I had been searching for hours and I found solutions as follow:

In my case, method 1 works.

Method 1:

1. choose the target > go to Build Phases > click Link Binary With Libraries > remove all libPods.a files

2. open Terminal > direct to your project > run:

     pod install
   

3. clean and build project

ref.1

Method 2:

1. open Terminal > direct to your project > run:

    pod deintegrate --verbose    
    pod install --verbose
   

ref.2

Method 3:

1. choose the target > go to Build Settings > click "+" sign

2. add 2 User-Defined Settings: [to the left = to the right]

    PODS_ROOT = ${SRCROOT}/Pods
   

and

    PODS_PODFILE_DIR_PATH = ${SRCROOT}/

Solution 4:

If you remove all pods from your target in the Podfile, e.g.

target 'myTarget' do
pod 'great-stuff', '~> 4.0'  // you deleted this last pod
end

you'll need to manually delete these builds steps from your Xcode target Build Phases:

• Check Pods Manifest.lock
• Copy Pod resources

Cocoapods (current stable version 0.37.2) does not perform this cleanup when you run pod install.

Solution 5:

Removing pods from the project and re-installing worked for me.

There is nice GitHub repository that can completely remove the pods from the project.

Just keep the backup of your PodFile and run below commands.

• gem install cocoapods-deintegrate
• gem install cocoapods-clean
• Go to the project directory and run pod deintegrate
• Again run pod clean
• Run pod install

Clean and run.
