Release ios-v3.4.0-beta.3 · mapbox/mapbox-gl-native

Stability and Swift compatibility

Fixed a crash that occurred during low-memory situations when multiple instances of MGLMapView were in the view hierarchy. (#6972)
Notification names and user info keys are now string enumeration values for ease of use in Swift. (#6794)

Fixed a memory leak that occurred when MGLStyleLayer instances were created and added to an MGLStyle. (#6904)
Changes to MGLSymbolStyleLayer’s textField and iconSize properties now take effect immediately. (#6928, #6932)
Fixed a crash that occurred when removing an MGLSource or MGLStyleLayer from an MGLStyle and adding it back to the same MGLStyle or another MGLStyle. (#7048)
A more informative exception is raised if you attempt to add an incorrectly initialized source to an MGLStyle or remove an incorrectly initialized source or style layer from an MGLStyle. (#7060)
Improved the performance of symbol style layers. (#7025)

Fixed a crash panning or zooming after adding a polyline or polygon annotation to the map. (#6888)
Fixed a crash calling -[MGLMapView viewForAnnotation:] with an annotation that has not been added to the map. (#6957)
-[MGLMapView viewForAnnotation:] now returns the user location annotation view when given the user location annotation. (#6957)
-[MGLMultiPoint replaceCoordinatesInRange:withCoordinates:] now raises an exception if the range extends beyond the current array of coordinates. To append coordinates to an existing polyline or polygon, use the new -appendCoordinates:count: method. (#6890)
Fixed an issue where view-backed annotations added while panning the map could become detached from the map and cause a crash. (#6924)
Fixed a crash that occurred when adding the same MGLAnnotation object to the map a second time. (#6924)
