TextEdit User Guide
You can use TextEdit to edit or display HTML documents as you'd see them in a browser (images may not appear), or in code-editing mode.
Note: By default, curly quotes and em dashes are substituted for straight quotes and hyphens when editing HTML as formatted text. (Code-editing mode uses straight quotes and hyphens.) To learn how to change this preference, see New Document options.
Create an HTML file
In the TextEdit app on your Mac, choose File > New, then choose Format > Make Plain Text.
Enter the HTML code.
Choose File > Save, type a name followed by the extension .html (for example, enter index.html), then click Save.
When prompted about the extension to use, click 'Use .html.'
View an HTML document
In the TextEdit app on your Mac, choose File > Open, then select the document.
Click Options at the bottom of the TextEdit dialog, then select 'Ignore rich text commands.'
Click Open.
Always open HTML files in code-editing mode
In the TextEdit app on your Mac, choose TextEdit > Preferences, then click Open and Save.
Select 'Display HTML files as HTML code instead of formatted text.'
Change how HTML files are saved
Set preferences that affect how HTML files are saved in TextEdit.
In the TextEdit app on your Mac, choose TextEdit > Preferences, then click Open and Save.
Below HTML Saving Options, choose a document type, a style setting for CSS, and an encoding.
Select 'Preserve white space' to include code that preserves blank areas in documents.
If you open an HTML file and don't see the code, TextEdit is displaying the file the same way a browser would (as formatted text).
With an all-new design that looks great on macOS Big Sur, Xcode 12 has customizable font sizes for the navigator, streamlined code completion, and new document tabs. Xcode 12 builds Universal apps by default to support Mac with Apple Silicon, often without changing a single line of code.
Designed for macOS Big Sur.
Best Code Editor For Mac 2020
Xcode 12 looks great on macOS Big Sur, with a navigator sidebar that goes to the top of the window and clear new toolbar buttons. The navigator defaults to a larger font that's easier to read, while giving you multiple size choices. New document tabs make it easy to create a working set of files within your workspace.
Document tabs.
The new tab model lets you open a new tab with a double-click, or track the selected file as you click around the navigator. You can re-arrange the document tabs to create a working set of files for your current task, and configure how content is shown within each tab. The navigator tracks the open files within your tabs using strong selection.
Navigator font sizes.
The navigator now tracks the system setting for 'Sidebar icon size' used in Finder and Mail. You can also choose a unique font size just for Xcode within Preferences, including the traditional dense information presentation, and up to large fonts and icon targets.
Code completion streamlined.
Selenium for mac os. A new completion UI presents only the information you need, taking up less screen space as you type. And completions are presented much faster, so you can keep coding at maximum speed.
Redesigned organizer.
An all-new design groups all critical information about each of your apps together in one place. Choose any app from any of your teams, then quickly navigate to inspect crash logs, energy reports, and performance metrics, such as battery consumption and launch time of your apps when used by customers.
SwiftUI
SwiftUI offers new features, improved performance, and the power to do even more, all while maintaining a stable API that makes it easy to bring your existing SwiftUI code forward into Xcode 12. A brand new life cycle management API for apps built with SwiftUI lets you write your entire app in SwiftUI and share even more code across all Apple platforms. And a new widget platform built on SwiftUI lets you build widgets that work great on iPad, iPhone, and Mac. Your SwiftUI views can now be shared with other developers, and appear as first-class controls in the Xcode library. And your existing SwiftUI code continues to work, while providing faster performance, better diagnostics, and access to new controls.
Universal app ready.
Mac Os Code
Xcode 12 is built as a Universal app that runs 100% natively on Intel-based CPUs and Apple Silicon for great performance and a snappy interface.* It also includes a unified macOS SDK that includes all the frameworks, compilers, debuggers, and other tools you need to build apps that run natively on Apple Silicon and the Intel x86_64 CPU.
Updated automatically
When you open your project in Xcode 12, your app is automatically updated to produce release builds and archives as Universal apps. When you build your app, Xcode produces one binary 'slice' for Apple Silicon and one for the Intel x86_64 CPU, then wraps them together as a single app bundle to share or submit to the Mac App Store. You can test this at any time by selecting 'Any Mac' as the target in the toolbar.
Test multiple architectures.
On the new Mac with Apple Silicon, you can run and debug apps running on either the native architecture or on Intel virtualization by selecting 'My Mac (Rosetta)' in the toolbar.
Multiplatform template
New multiplatform app templates set up new projects to easily share code among iOS, iPadOS, and macOS using SwiftUI and the new lifecycle APIs. The project structure encourages sharing code across all platforms, while creating special custom experiences for each platform where it makes sense for your app.
Improved auto-indentation
Swift code is auto-formatted as you type to make common Swift code patterns look much better, including special support for the 'guard' command.
StoreKit testing
Python Editor Mac Os X
New tools in Xcode let you create StoreKit files that describe the various subscription and in-app purchase products your app can offer, and create test scenarios to make sure everything works great for your customers — all locally testable on your Mac.
