@jjatie jjatie commented Dec 26, 2017

Renderer, DataRenderer and AxisRenderer are now protocols instead of classes.

Slight more code, but allows for better type safety and removes a lot of unnecessary type conversion. It's a "Swift-ier" way.

This a resubmit of #2990 because there were major merge conflicts in that one.

* weak -> unowned (#3039)

* weak -> unowned

`ViewPortJob`s are owned by the Charts that make them. They are guaranteed to only exist while the chart exists. The `Transformer` and `ViewPortHandler` are supplied by the chart, so they will also only exist while the chart exists. Therefor none of them need to be `weak`, but can be `unowned` instead. It's a minor change in the code base (removing some guard statements), but it makes it much easier to discern how the framework is architected.

* pulled latest master

* Removed optionality from valueFormatter where appropriate (#3106)

* Removed optionality from valueFormatter where appropriate

In ChartBaseDataSet, `valueFormatter` never returned nil, and escaped early if trying to set it to nil. It appears this was made optional solely to provide lazy initialization. We now use a lazy var instead.

In AxisBase, the backing var `_axisValueFormatter` would never be treated as nil, and appears to be made optional solely to provide lazy initialization. We now use a lazy var instead. In `valueFormatter` we can remove the `nil` check, but leave it optional to keep the same functionality.

* Fixed axisLabels calculation

* Fill rewrite (#3084)

close #3140
* Fill is now a protocol

Different fill logic is broken up into separate classes. This has a few benefits:
1. It makes the `Fill` types more readable (logic is grouped together)
2. No optionals
3. Most importantly it allows consumers to create new Fill types without looking into the framework.

* Added super.init() for objc

* Updated Fill access

No need to subclass existing fills now that the system is more flexible. If functionality is needed from another fill, user can call it within their own `fillPath(context: CGContext, rect: CGRect)` implementation.

* Updated Fill Names

* Update Fill.swift

update code style

* update to Swift 5, Xcode 13.5.1, and fix warnings

* fix all compile errors and wrong symbols either by git or me.

* revert back to convenience init for BarChartDataSet
fix ChartDataTests compile errors: use new API dataSet(forLabel:, ignorecase: )

* actually, I compared the old master and find this is a mistake while merging to make init(label:) in BarChartDataSet. It should be in ChartDataSet.

* fix -0.0 issue in 4.0 merge. fix func calculateLegendOffsets in BarLineChartViewBase due to mistaking added back offsetBottom += xAxis.labelRotatedHeight. see #4277 for details
now bar & horizontal bar chart tests should pass.

* fix pie chart UT failures. didSet will no be called in init(), so we call it manually
also fix set.valueFormatter in data setter

* fix line chart UT failures

* Remove `isIndirectValuesCall`

* Bump Travis to Xcode 12

* Remove misuse of `count` (#4461)

* Remove misuse of `count`

* Fix protocol method name

* Update ChartColorTemplates.swift

use fallbackColor for `colorFromString()`

* Revert "Update ChartColorTemplates.swift"

This reverts commit b4111fd.

* switch to source compiling swift code

* fix Carthage error after changing to source compile. Carthage/Carthage#3019

there is a workaround mentioned [here](Carthage/Carthage#3019 (comment))
making travis to build from carthage.sh until the root issue is fixed.

* update project settings

* recreate iOS+tvOS images due to iOS14 SDK uncertain changes.

* Remove unnecessary ternary in boolean expression (#4435)

* Remove internal use of datasets (#4459)

* weak -> unowned (ChartsOrg#3039)

* weak -> unowned

`ViewPortJob`s are owned by the Charts that make them. They are guaranteed to only exist while the chart exists. The `Transformer` and `ViewPortHandler` are supplied by the chart, so they will also only exist while the chart exists. Therefor none of them need to be `weak`, but can be `unowned` instead. It's a minor change in the code base (removing some guard statements), but it makes it much easier to discern how the framework is architected.

* pulled latest master

* Removed optionality from valueFormatter where appropriate (ChartsOrg#3106)

* Removed optionality from valueFormatter where appropriate

In ChartBaseDataSet, `valueFormatter` never returned nil, and escaped early if trying to set it to nil. It appears this was made optional solely to provide lazy initialization. We now use a lazy var instead.

In AxisBase, the backing var `_axisValueFormatter` would never be treated as nil, and appears to be made optional solely to provide lazy initialization. We now use a lazy var instead. In `valueFormatter` we can remove the `nil` check, but leave it optional to keep the same functionality.

* Fill rewrite (ChartsOrg#3084)

close ChartsOrg#3140
* Fill is now a protocol

Different fill logic is broken up into separate classes. This has a few benefits:
1. It makes the `Fill` types more readable (logic is grouped together)
2. No optionals
3. Most importantly it allows consumers to create new Fill types without looking into the framework.

* Added super.init() for objc

* Updated Fill access

No need to subclass existing fills now that the system is more flexible. If functionality is needed from another fill, user can call it within their own `fillPath(context: CGContext, rect: CGRect)` implementation.

* Updated Fill Names

* Update Fill.swift

update code style

* update to Swift 5, Xcode 13.5.1, and fix warnings

* fix all compile errors and wrong symbols either by git or me.

* revert back to convenience init for BarChartDataSet
fix ChartDataTests compile errors: use new API dataSet(forLabel:, ignorecase: )

* actually, I compared the old master and find this is a mistake while merging to make init(label:) in BarChartDataSet. It should be in ChartDataSet.

* fix -0.0 issue in 4.0 merge. fix func calculateLegendOffsets in BarLineChartViewBase due to mistaking added back offsetBottom += xAxis.labelRotatedHeight. see ChartsOrg#4277 for details
now bar & horizontal bar chart tests should pass.

* fix pie chart UT failures. didSet will no be called in init(), so we call it manually
also fix set.valueFormatter in data setter

* fix line chart UT failures

* Remove `isIndirectValuesCall`

* Bump Travis to Xcode 12

* Remove misuse of `count` (ChartsOrg#4461)

* Remove misuse of `count`

* Fix protocol method name

* Update ChartColorTemplates.swift

use fallbackColor for `colorFromString()`

* Revert "Update ChartColorTemplates.swift"

This reverts commit b4111fd.

there is a workaround mentioned [here](Carthage/Carthage#3019 (comment))
making travis to build from carthage.sh until the root issue is fixed.
