Hello mjza, Could you tell me please, where do I set TKTokenOperationConstraint? Apple documentation is so poor. Thank you.

You can try something like this: let rangeA = 1...10 let rangeB = 14...22 let numsBetweenRanges = Set(rangeA).symmetricDifference(Set(rangeB)) let missingNums = Array(numsBetweenRanges).sorted().filter { num in !range1.contains(num) || !range2.contains(num) } print(missingNums) // Output: [11, 12, 13]

Same here
