=Qt for iOS known issues in 5.4.0=


* Qt requires iPhoneOS.8.0.sdk and Xcode 6 (or newer) to be installed, and qmake will inform if this is not the case.<br /> After installing latest version of Xcode you might still get a warning about the current Xcode version being<br /> too old. The solution is to remove .qmake.stash inside your build folder before re-running qmake.
* Line edits inside dialogs might not be able to get focus and bring up the keyboard. The solution is to<br /> call QWidget::activateWindow() on the dialog after it has been shown.
* QQuickWidget and QOpenGLWidget are not yet supported on iOS.
=Qt for iOS known issues in 5.3.1=
==Qt Positioning==
Linking of position based applications fails due to an incorrect <span class="caps">CLASS</span>_NAME. For more details and a temporary workaround see <span class="caps">QTBUG</span>-39843. The fix can be tracked via https://codereview.qt.io/#/c/88290/ .
=Qt for iOS known issues in 5.3.0=
==Qt Creator==
* When switching from simulator to device in insource building you should not import the old build settings (<span class="caps">QTCREATORBUG</span>-11067)
=Qt for iOS known issues in 5.2.x=
* Known and open [https://bugreports.qt.io/issues/?filter=14129 bugs] ''[bugreports.qt.io]''
==Building / running==
==Qt Creator==
* Debugging on device has a slow startup (<span class="caps">QTCREATORBUG</span>-10884)
* Changing the shadow build directory does not update the run path (just in the ui, the correct one is used) (<span class="caps">QTCREATORBUG</span>-11080)
* When switching from simulator to device in insource building you should not import the old build settings (<span class="caps">QTCREATORBUG</span>-11067)
==Qt Quick 2==
* Using the Drag attached property causes crash. Drag and drop is not supported on iOS in 5.2, and the QML2 implementation of the property does not handle a platform that doesn’t support DnD.
==Examples==
* Examples do not compile for iOS if they are located in a non-iOS Qt tree. If you are using Qt Creator, you need to explicitly select the iOS Qt version from the combo box in the examples browser before opening and compiling the example for iOS.
