Just tested this in our game that uses quick tap controls. It indeed resolved the memory leak, and even more importantly, it eliminated the horrible input stutters / frame drops that were making the game unplayable even on new iPhones. Very much looking forward to seeing this merged, great work! |

Thanks! |

Good stuff! Thanks all. Maybe the problem was hidden for us since the touch_delay was set to 0.01, but will definitely give it a try on the next RC, |

Fixes #66422 for 3.x branch. A fix for master is at #69201.
Replaces gesture recognizer with touch events directly from the view.
Rationale:
Gesture recognizers retain all touch events until their
stateproperty changes to "cancelled" or "ended."The custom recognizer in the project fails to implement this requirement.
Setting the state to "ended" in the recognizer resolves the leak but introduces runtime assertions in logic that relied on an unending recognizer.
By forwarding the touch events directly from the view to Godot removes the need for a gesture recognizer.
Furthermore, the motivation for delaying touch inputs looks to be resolved too. (See #39624)
This branch removes the delay from touch events, putting iOS on parity with other platforms.
Project setting
input_devices/pointing/ios/touch_delayhas been removed as a consequence.
