Skipped installing .framework binary due to the error

I'm using Carthage and getting this error with a dependency or two:

Skipped installing mixpanel-swift.framework binary due to the error: "Incompatible Swift version - framework was built with 3.1 and the local version is 4.0."

enter image description here

I understand generally what Carthage is seeing as the problem, but I haven't found a satisfactory answer on my own or looking through other issues posted that feels as clean or solid as I'm assuming it should be.

I've seen carthage bootstrap --platform iOS --no-use-binaries as a potential solution, but I can't tell if thats solving the actual problem I'm having or not, or if it is the best solution long term?

Any help on a solution or guiding me to my way there? Thanks!

Solution

  • To solve this you need to use the Swift 4 version of Mixpanel. It is failing because the code you are getting from Github is for Swift 3. On their Github page they say you should use the Swift 4 branch - Mixpanel Swift 4 branch. I think your Cart file needs to use: github "mixpanel/mixpanel-swift" "swift4"
