[ios] No signing certificate "iOS Distribution" found

I am trying to sign an app with my client's certificates. I have received the following file from the client

I tried installing the ios_distribution certificate and the key (.p12). Also I have installed the provisioning profile. Now when I try to sign the app with the provisioning profile, it does show up in the drop down but I get the following error:-

No "iOS Distribution" signing certificate matching team ID "7S977Lxxx" with a private key was found

How can I solve this issue? Any help is appreciated.

Tried the above solutions with no luck ... restarted my mac solved the issue...

Goto Xcode -> Prefrences and import the profile

Our solution was to run

fastlane match

as I forgot we setup a Matchfile.

I got the "No signing certificate" error when running Xcode 11.3 on macOS 10.14.x Mojave. (but after Xcode 12 was released.)

I was also using Fastlane. My fix was to set generate_apple_certs to false when running Match. This seemed to generate signing certificates that were backwards-compatible with Xcode 11.3

Match documentation - https://docs.fastlane.tools/actions/match/

This is the relevant section of my Fastfile:

platform :ios do
  lane :certs do
    force = false
    match(type: "development", generate_apple_certs: false, force: force, app_identifier: "your.app.identifier.dev")
    match(type: "adhoc",       generate_apple_certs: false, force: force, app_identifier: "your.app.identifier.beta")
    match(type: "appstore",    generate_apple_certs: false, force: force, app_identifier: "your.app.identifier")
  end

  ...

Double click and install the production certificate in your key chain. This might resolve the issue.

Solution Steps:

1. Unchecked "Automatically manage signing".

2. Select "Provisioning profile" in "Signing (Release)" section.

3. No signing certificate error will be show.

4. Then below the error has a "Manage Certificates" button. click the button.

5. This window will come. Click the + sign and click "iOS Distribution". xcode will create the private key for your distribution certificate and error will be gone.

I had the same issue and I have gone through all these solutions given, but none of them worked for me. But then I realised my stupid mistake. I forgot to change Code signing identity to iOS Distribution from iOS Developer, under build settings tab. Please make sure you have selected 'iOS Distribution' there.
