Devices, methods, and graphical user interfaces for navigating between user interfaces, displaying a dock, and displaying system user interface elements

An electronic device, comprising:

• a touch-sensitive display;
• one or more processors;
• and
• memory storing one or more programs, wherein the one or more programs are configured to be executed by the one or more processors, the one or more programs including instructions for:
• concurrently displaying, on the touch-sensitive display, a first application and a second application, wherein the first application and the second application are both displayed along at least a portion of a respective edge of the touch-sensitive display;
• while concurrently displaying the first application and the second application, detecting a first edge-swipe gesture at a respective location along the respective edge of the touch-sensitive display that includes movement of a contact from the respective location along the respective edge of the touch-sensitive display onto the touch-sensitive display;
• and
• in response to detecting the first edge-swipe gesture:
• in accordance with a determination that the respective location of the first edge-swipe gesture corresponds to a location of the first application on the touch-sensitive display, that the first application is currently associated with standard edge-swipe gesture criteria, and that the first edge-swipe gesture meets the standard edge-swipe gesture criteria, wherein the standard edge-swipe gesture criteria include a first set of one or more requirements that must be met in order for the standard edge-swipe gesture criteria to be met, performing a system operation that includes displaying a system user interface at a portion of the touch-sensitive display that was previously occupied by at least a portion of the first application and at least a portion of the second application;
• in accordance with a determination that the respective location of the first edge-swipe gesture corresponds to a location of the second application on the touch-sensitive display, that the second application is currently associated with the standard edge-swipe gesture criteria, and that the first edge-swipe gesture meets the standard edge-swipe gesture criteria, performing the system operation;
• in accordance with a determination that the respective location of the first edge-swipe gesture corresponds to a location of the first application on the touch-sensitive display, that the first application is currently associated with enhanced edge-swipe gesture criteria, and that the first edge-swipe gesture does not meet the enhanced edge-swipe gesture criteria, wherein the enhanced edge-swipe gesture criteria include the first set of one or more requirements that must be met in order for the standard edge-swipe gesture criteria to be met and also include a second set of one or more requirements that must be met in addition to the first set of one or more requirements in order for the enhanced edge-swipe gesture criteria to be met, forgoing performing the system operation;
• and
• in accordance with a determination that the respective location of the first edge-swipe gesture corresponds to a location of the second application on the touch-sensitive display, that the second application as currently displayed is associated with the enhanced edge-swipe gesture criteria, and that the first edge-swipe gesture does not meet the enhanced edge-swipe gesture criteria, forgoing performing the system operation.

A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which, when executed by an electronic device with a touch-sensitive display, cause the electronic device to:

• concurrently display, on the touch-sensitive display, a first application and a second application, wherein the first application and the second application are both displayed along at least a portion of a respective edge of the touch-sensitive display;
• while concurrently displaying the first application and the second application, detect a first edge-swipe gesture at a respective location along the respective edge of the touch-sensitive display that includes movement of a contact from the respective location along the respective edge of the touch-sensitive display onto the touch-sensitive display;
• and
• in response to detecting the first edge-swipe gesture:
• in accordance with a determination that the respective location of the first edge-swipe gesture corresponds to a location of the first application on the touch-sensitive display, that the first application is currently associated with standard edge-swipe gesture criteria, and that the first edge-swipe gesture meets the standard edge-swipe gesture criteria, wherein the standard edge-swipe gesture criteria include a first set of one or more requirements that must be met in order for the standard edge-swipe gesture criteria to be met, perform a system operation that includes displaying a system user interface at a portion of the touch-sensitive display that was previously occupied by at least a portion of the first application and at least a portion of the second application;
• in accordance with a determination that the respective location of the first edge-swipe gesture corresponds to a location of the second application on the touch-sensitive display, that the second application is currently associated with the standard edge-swipe gesture criteria, and that the first edge-swipe gesture meets the standard edge-swipe gesture criteria, perform the system operation;
• in accordance with a determination that the respective location of the first edge-swipe gesture corresponds to a location of the first application on the touch-sensitive display, that the first application is currently associated with enhanced edge-swipe gesture criteria, and that the first edge-swipe gesture does not meet the enhanced edge-swipe gesture criteria, wherein the enhanced edge-swipe gesture criteria include the first set of one or more requirements that must be met in order for the standard edge-swipe gesture criteria to be met and also include a second set of one or more requirements that must be met in addition to the first set of one or more requirements in order for the enhanced edge-swipe gesture criteria to be met, forgo performing the system operation;
• and
• in accordance with a determination that the respective location of the first edge-swipe gesture corresponds to a location of the second application on the touch-sensitive display, that the second application as currently displayed is associated with the enhanced edge-swipe gesture criteria, and that the first edge-swipe gesture does not meet the enhanced edge-swipe gesture criteria, forgo performing the system operation.
