2020年后的解决方案

终于有了 Xcode 12

在 Xcode 12 发布后，我们现在可以轻松更改导航器字体大小.

编码时不再盲目！;)

如何在 macOS 上更改系统系统的分辨率?

2020 年之前的解决方案 - 又名我的早期答案

目前更改分辨率的唯一方法是更改​​系统首选项.系统偏好 >显示 >从默认显示"更改分辨率选项到缩放"并根据需要选择.

在 Xcode 7 和 Alcatraz 之后

请注意，自 Xcode 8 起不再支持插件.Alcatraz 仅适用于 Xcode 7

Is there any way to change the font size of the navigator panel in xcode? I've managed to change the font size in the edit window with preference->font & color, but that does not change the font size of the navigator.

Solution after 2020

Finally with Xcode 12

After the release of the Xcode 12 now we're able to change the Navigator Font Size easily.

What’s New in Xcode 12

Xcode 12 includes Swift 5.3 and SDKs for iOS 14, iPadOS 14, tvOS 14, watchOS 7, and macOS Big Sur ...

Refined user interface for macOS Big Sur

• Document tabs open any type of document, including logs, asset catalogs, and UI files, in a lightweight editor tab

• Toolbar, icons, and sidebar designs match the beautiful new aesthetic of macOS Big Sur

• Navigator fonts track the size of the system setting or can be manually set to a custom size

• Organizer is completely redesigned and reports new app metrics, such as hitches in animation and scrolling

How

• Open Xcode's preferences
• Find the General Tab
• Find the new Navigator Size

Its default value is matched the system's Resolution. (check my early answer).

Now you can also choose Small, Medium, or Large.

No more getting blind while coding! ;)

How to change system system's Resolution on macOS?

Solution before 2020 - AKA My Early Answer

Only way to change Resolution is changing system preferences for now. System preferences > Displays > Change resolution option from "Default for display" to "Scaled" and choose as you wish.

After Xcode 7 and the Alcatraz

Please note that plugins are no longer supported since Xcode 8. Alcatraz is available for Xcode 7 only
