Release notes for 100.3

This page provides details about enhancements in the 100.3 release of ArcGIS Runtime SDK for iOS. It also lists this release's deprecations, resolved issues, and known issues.


This section describes new features and improvements.

Web scenes

As part of the improved support for 3D Web GIS capabilities of ArcGIS location services, you can now display web scenes from ArcGIS Online or ArcGIS Enterprise in your ArcGIS Runtime based apps. Web scenes can be quickly authored by apps such as ArcGIS Pro and Scene Viewer and then easily consumed by your apps, respecting the content, symbology, pop-ups and other settings that the author configured in the web scene. For more information about Runtime support for web scenes, see Runtime support for web scenes.

In addition, 3D content originating from scene layers can now be identified and selected, and their display can be customized through renderers in the web scene. And feature layers can be displayed with 3D symbols originating from web styles in ArcGIS Online or ArcGIS Enterprise.

Scene analysis

  • Interactive distance measuring is now supported in 3D. You can measure horizontal, vertical, and direct distances between two locations in a scene view.
  • Viewshed analysis has been enhanced to support full 360 degrees horizontal field of view. Previously, only a maximum of 120 degrees was supported.


Arcade expressions are now supported:

  • In pop-ups for layer types (for example, feature layers) that support pop-ups. They're defined using the expression property on a pop-up definition.
  • In label definitions for feature layers and graphic overlays. They're defined in JSON using the expression property on the labelExpressionInfo object.
  • In visual variables within renderers defined for feature layers in web maps and mobile map packages. Feature layers must be rendered in static mode to honor visual variables in renderers.

See this SDK's API reference for details on using Arcade. For general information on Arcade and Arcade's function reference, see the ArcGIS Arcade guide.


WMS support has been enhanced:

  • WMS layers are now time aware and support filtering their contents based on a time range or time instant.
  • You can discover available styles in the service and set the style of a layer to customize its display.
  • You can now specify custom parameters to be sent to the service. This is useful, for instance, if the service requires custom authorization parameters in the HTTP requests.
  • WMS layers now automatically display attribution information of the service in a map view or scene view .


Improvements have been made to provide finer control over label placement. These refinements allow for a more consistent display of labels when using mobile map packages (.mmpk files) generated from ArcGIS Pro. You can now do the following:

  • Allow overlap of a label with other features or labels based on weights to assign relative importance and define priorities when there is a conflict
  • Specify an offset distance of a label from the symbol based on screen units.
  • Stack multiple lines of text with custom line separators and choose whether line break should occur before or after the separator, whether the separator should be visible, etc. Previously, only whitespace characters were considered for inserting line breaks.

Query support for map image layer

You can now query sublayers and tables from a map image layer in the same way you query feature layers. The query can be based on attributes and/or spatial relationships and can also be used to return summary statistics or related features. Also, a new method has been added to conveniently load all the sublayers and tables contained in the layer so that their data can be accessed.

Military symbology

Support for App-6(B) and App-6(D) military symbology specifications has been added. You can use the corresponding style files to display symbols based on these standards in your ArcGIS Runtime apps.


Pop-ups now support displaying values from expressions based on the Arcade language. This support is useful, for instance, when you want to display a derived or computed value based on the existing attributes of a feature. Expressions can be used in pop-up fields, charts, and media. In addition, pop-ups now support Display P3 images generated on newer iOS devices and macOS machines that have wide color gamut displays.

Sketch Editor

Sketch Editor has been enhanced to allow convenient sketching of common shapes such as rectangles, squares, circles, ovals, triangles, and arrows. In addition, sketches can be easily moved, resized, and rotated using on-screen anchors.

Key-value observing (KVO)

KVO enabled properties now support reporting the old value and also automatic un-registration for Swift observers.

Performance improvement in rendering

Display of graphics and features has been fine-tuned to improve performance and render consistently at 60 FPS as much as possible depending upon the available hardware and amount of data rendered. While some performance degradation is inevitable as the amount of data to render increases, in some cases when working with large amount of data the frame rate has improved by up to 20% for points, 30% for polylines, and 50% for polygons as compared to previous releases.


The toolkit has been upgraded to use Swift 4, and adopt Apple's UI guidelines for iPhone X. In addition, a new Time Slider component has been added to allow filtering the content of time-aware layers based on a time range or instant. You can auto play progression of the time slider and customize the look & feel of the component to match your app's styling

Guide documentation

  • Expanded and reorganized layers topics. A new table summarizes supported layers and their capabilities.
  • Expanded and reorganized map and scene documentation.


Support for iOS 10 is deprecated. A minimum of iOS 11 will be required at a future release.
