Yep – this happens. The way to handle it (you can’t get sprite-kit to NOT call didBegin multiple times in some circumstances) is to make sure that your contact code accommodates this and that handling the contract multiple times does not cause a problem (such as adding to the score multiple times, removing multiple lives, … Read more

LastCommunicationDate is a string, but you are converting it to a Double. Try this instead: let lastCommunicationDate = “2022-01-21T10:58:21.367” //Create dateformatter to convert string to Date let isoDateFormatter = ISO8601DateFormatter() isoDateFormatter.formatOptions = [ .withFullDate, .withTime, .withColonSeparatorInTime, .withFractionalSeconds ] let isoDateFormatter2 = ISO8601DateFormatter() isoDateFormatter2.formatOptions = [ .withFullDate, .withTime, .withColonSeparatorInTime ] let date = isoDateFormatter.date(from: lastCommunicationDate) ?? … Read more
Here is my version where I filter on a range based on first value of the array and the coef variable, based on the result I slice away those elements already counted and filter again on the smaller array in a loop. This solution requires the input array to be sorted in ascending order func … Read more
