As was recently resolved for Android, I have a test app (attached) which automatically advances through months, to make leak testing easy.
As I was testing SyncFusion 126.96.36.199 for Android, very happy with that fix, I also tested iOS as I'm shipping a cross-platform app.
There is a steady memory leak under iOS as well, not anywhere near as severe as the Android one, but still needs addressing.
I have an Instruments recording proving the leak but compressed is still about 300MB so cannot attach here.
On an iPhone 6+ it crashes between 300 and 400 advances
On an iPod Touch 6 (where I recorded the Instruments) it crashes between 180 and 230 advances.
These sound like a lot but this is not representing a single set of user actions. It's the total number of times the sfSchedule control is shown within a run of the program. As a leak, this still means the iPhone will eventually crash. Our users typically flick through several months of their calendar each time they use the app, sometimes skimming through an entire year's worth. This implies crashing as often as once a month for our more active users.
