There is a function .retry() in Combine that helps to retry a request. Although it is not enough just to call retry() to achieve retring logic. The retry() function does not do another request but it re-subscribes only to a publisher. To make another request the tryCatch() might be used. In the code below if the first call fails there are three attempts to retry (retry(3)):

brew install redis

To have launchd start redis now and restart at login:

brew services start redis

1. Clone your fork:

git clone [email protected]:YOUR-USERNAME/YOUR-FORKED-REPO.git

2. Add remote from original repository in your forked repository:

cd into/cloned/fork-repo
git remote add upstream git://github.com/ORIGINAL-DEV-USERNAME/REPO-YOU-FORKED-FROM.git
git fetch upstream
